but the problem is i dont have oscilloscope,but the voltage is not dropping on pin 6 of q31 it stays at 2.1v and display on the screen is ok and no white screen issue anymore till now the laptop still on without coming back the issue. is it possible the problem on the q33 has cold solder joint?
Yes, if the problem does not come back, it could be what you said, a cold solder joint, when the transistor works for a while, the heat generated from the transistor opens the solder joint.
Firstly glad you managed to fix the issue this is why i like this forum there are so many knowledgeable people who are willing too take time and help/educate others and share there schematics (as we know some are only available if paid for).

Hello bro i fixed many times this model just reheat or remove and put back again the inductor coil on power supply to processor, this is the common issue for this model i tried it mostly rejected from service centers of acer
hello did you fixed this issue?
i did this model many times by replacing the inductor coil on cpu power supply
the coil label is R15/R15A.
it is weired, sometimes you only need to reheat that coil and the problem solve
i also have this problem with acer es1-432 the laptop works ok you can install only 64 bit windowa 10 , the problem is whenever the laptop goes to sleep mode you can never wake it up unless ofcourse you turn it off. any suggestion where to find the fault of these board. all voltages were present . need help. thanks.
